BENJAMIN LIVERMORE, OF HARTLAND, VERMONT.

DEVICE FOR, H AND-PRINTlNG.

Specification forming part of Letters Patent No. 39.296, dated July 21,1863.

To all whom it may concern:

Be it known that I, BENJAMIN LIvERMoRE, of Hartland, in the county ofWindsor and State of Vermont, have invented a new and improvedHand-Printing Device or Mechanical Typographer; and I do hereby declarethat the following is. a full, clear, and exact description of the same,reference being had to enlarged face view of the combination-type;

Fig. 5, a view of the alphabet, as formed by the combination-type.

Similar letters of reference indicate corresponding parts in the severalfigures.

' The object of this invention is to obtain a portable device which maybe held in the hand .and operated with the greatest facility forprinting direct upon paper or other suitable material.

To this end the invention consists in the employment or use of acombination-typethat is to say, a type composed of several sections,arranged andcombined in such a manner that .any oneof the sections maybe used separately, and certain parts used combined, in order to formthe dii'erent letters ofthe alphabet, as hereinafter set forth. 4

The invention also consists in the employ ment or use of finger piecesor keys, arranged in a novel way withlevers, for the purpose ofoperating the several parts of the type, and also in a certain meansemployed for causing the type to traverse or move so that proper vspaces may be allowed between the impressions, and the type allowed toadjust itself properly "at the termina-tion of each line for theprinting of a succeeding one.

The invention further consists in a means employed for moving or feedingthe paper. along at the termination of each line as it is printed.

To enable those skilled in the art to fully' understand,.construct, anduse my invention, l will proceed to describe it.

A represents-a metal case, in which the working parts 1 of the deviceare fitted. This caseat one' end, a, is -of semi-cylindrical form,

and within 'said part a a cylinder, b,is placed,

on which the paper c,to be printed upon, is wound as it is -printedupon. (See Figs. 1 and 2.)- f

B is a plate, which is placedon'the bottom of the case A, and is securedthereto, at its outer end, by a rivet, d, on which the plate B isallowed to work freely.

C is a curved rack-bar,which is permanently secured to the bottolm ofthe caseA, and underneath which the plate Bis allowed to work freely,the bar C having its rank on its concave edge. On the plate B there issecuredl by a fulcrum-pin, e, a bent lever, D, which is acted upon by aspring, j', and has a pawl,E, attached to it by a pivot, g. 4This pawlhas two prongs, h'h/,ne of which,h, engages with the rack-bar C. The useof the other prong, h', will be presently shown.

F is a holding-pawl,whichengages with the rack-bar G and'is providedwith au arm, i, which has a projection, j, nearjts outer end, as shownin Fig. 1. The pawl E is actedupon by a spring, k, whichkeeps it engaged.with the rack-bari), and the holdingpawl Fis acted upon by a spring, l,which performs a like oce.

From the above description it will be seen that by forcing or pressingthe longer arm of 'the lever D. inward or toward the cylinder b,

that the pawl E will be raised and'slipovera tooth of the bar C, andwhen Asaid leveris relieved of the pressure the spring f will throw thelever D back to its original position, and the inner end of the plate Bwill be raised in consequence of the pawl E catching intothe rack-bar.The inper end of theplate B is thus elevated from the lower to the upperedge of the case A, the latter, when tbe device is in use, being held-inan inclined position in the hand of the operator. When the plate B hasreached the upper, end of the ease A, the

prong h, which vifs the pawl E proper, passes over a projecting part, m,on the rack-.bar and causes the prong 71.' to act against. theprojection 7 on the arm 1', and throntthe holdingpa'wl Font from therack-bar (l, and admit of the plate B falling, by its own gravity, tothe levers, l1, are fitted on a conunon fulcrumpin, tm'. lhe form otthese levers is clearly shown in Fig'. 2.-

l represents what l term a "combination type. It is formed of sixditi'erent. parts, designated by l 1', 2 2', and 3 3'. as shown in Fig.4. '.lbepartsl l' and 2 2' i'orm a hollow square, while the parts 3',3',are ot' V form and within said square, 3' beingl inverted andha-ving itsangle adjoining the angle ot'3, as shown clearly in Fig. 4. By means ot'these six parts the alphabet is formed, as shown in Fig'. 5. 1`hepart 3'when pressed against the paper forms the letter A. 3', 3.',`and 2 formthe letter 1%; 3, 2,and 1',the1etterb; 3",1', and 2', the letter-l.) 1,1', and 2, the. letter E; 2 and ],.the letter F; 3', 2,`and l, thcletter G; 3 and 2, the letter l1; 2, the letter l; 1.l and 2', theletter J; 3, 3', and 2, the letter K; 2 and 1 the letter L; 3, 2, and2', the letter M; l, 2, and 2', the letter N; l, l' 2, and 2', theletter 0; 3, 1. and-2, the letter P; 3, 1, and 2', the let- 'errQ; 3 and2, the letter lt.; 1, 2', and 3', the

letter S; 1 and 3", the letter 1; 2, 2', and 1', the letter U;3,theletter V; 3',2, and 2', the letter W; 3 and 3', the letter X.; 3and 1',the letter Y; 1, 1', and 2', the letter 7. 'l`he levers H areconnected one to each ofthe parts ot' the type, as shown at ln, in lfig.2. and each lever H at its lowervcnd is provided with a pin, o, saidpins projecting laterally from one lside ofthe levers. The position ofthese pins ted over the pins o of the levers H, and the inner notches,1', arettted in the notchedledge q. The notchesr are made sniiieientlywide to admit of the arms K having acertain degree ot' play on the ledgeq, as will be seen by referring to Fig. 2. rllhe. outer ends of thenarms Kl are connected by pivots s to levers t,

which have their fulcra u at opposite sides of the case A, there heiliga. lever, t, for each. arm K, and each lever t has a key orfinger-piece, L, attached 'to it, each of which is marked correspondingto the part of the typewith which it is connected through the `...edinmot' the le-A ver AThe pivots s of -the levers t are about in line withthe pivot or rivet d ot' the plate i. -ly pressing` inward any one ofthe keys or iinger-pieces l1,the part ot' the type. l which is connectedwith it will be raised, andinst pre.- vioustothis, by theback wardmovement of the key, the plate B was raised one notch in the barC, toadmit. ota propel-space beingI between .th-e letters or impressions onthe paper. lhe paper c to be printed upon passes over the type I uponthe cylinder b i'rom a roller, M, which basa spring, r, bearing upon itto prevent iti'rom casually turning. A

Nrepresents a pad, which is saturated with -ink or coloring material. Apiece oi' paper havingainixture ot coloring matter and grease rubbedover it will answer. r1`his pad or paper is secured by springs if, tothe under side ofthe lid t) ot' thccase. The impression is given by theparts ot the type. pressing' the paper in contacty with the pad N. 'lhekeys 0r. linger-pieces Il may ,bc readily oymrated, either singly or twoormoreat aV time, so as to form the several letters. The lines, it will.be seen, are printed on the paper in curved form, owing to the curvedpath the lplate B describes in its upward n'iovement, and at thetermination ot' each line the plate 'l5 drops, owing to the throwing`out of the holdingpawl, and thc paper c is moved. a. triiie upon thecylinder b at the first upward movement ot' the plate B, so as to causea proper space between the lines. This movement of the paper c iseii'ected as follows: As the lever D is pressed` inward at its firstmovement in commencing.,r a. line, the. end a. otl its longest arm comesin contact with a 'sliding pawl, l,

which engages with a ratchet, b', on one end" of the cylinder b. 'liiispawl l is at the lower side of the case. A, and connected thereto by aswinging plate, ai', and it, is provided at its frontend with a barb,c', which catches over aprojection, d', ou a pawl, which works on apivot, e', and which lalso eng-ages with the ratchet b'.

'R is a spring', which bears or acts 'against both pawls l? Q, and has atendency to keep both paw'ls engage with the. ratchctb when theA pawl lis shoved forward, and also to throw the pawl l back from the ratchet.The pawl Q is a holding,` one, and prevents the cylinder b f'om casuallyturning while the pawl P is thrown back 'by the sprinf. By pressing downthe back end of the pawl Q, both pawls will be disengaged from theratchet b' and thc paper c adjusted as desired.

l would remark thatnumerals may be formed by the combined type I, theseveral parts being used singlyand Icoi'nbiue-d so as to approximate asnearly as possible to the known form of the same.

Raving thus described my invention, what I`claim as new, and'desire ltosecure by Let ters Patent, is-

1. The combination-type I, formed ot' a. se-

-of the type.

3. The plate '3rackbar C, and lever D, the latter being provided withthe pawls E F,

' provided, respectively, with prongs 'or arms h' fi', for the purposeof feeding 'or moving the type across the paper, as set forth.

4. Counecring the arms K with the leverD '0, as set forth.

of plate E through the medium of the bar or arm J, lfor the purpose ofmoving the type across the paper simultaneously with the giving of theimpression, or just; before the im.

pression is given, as set forth.

5. The two pawls P Q, arranged, as shown, in connection with the ratchetb and the leverD o f the plate B, -for moving the paper B EN J AMIN LIVERMORE.
